Kazeshini

風死

He is the physical manifestation of Hisagi Shuuhei's Zanpakuto. The spirit of Kazeshini appears as a dark figure that closely resembles a shadow. He possesses long black hair and wields a weapon similar to Shuuhei's Shikai. True to his appearance, he is violent and prone to rampages, taking pleasure in slashing his opponents. His behavior may be the reason Hisagi dislikes his zanpakutō.
Upon release, it transforms into a kusarigama-like weapon featuring two blades curving in opposite directions, linked by a long chain. Although Shuuhei dislikes the weapon's shape because it is "shaped like something meant to reap life itself," he is extremely proficient in its use. He can employ the blades as both hand-to-hand weapons and projectiles, using the chain to make their paths unpredictable.
